Abstract
Description
- This invention relates to an apparatus for opening a flatly folded tube of synthetic resin or the like material and fitting same on a container or the like.
- Examples of prior art apparatuses of this type are shown in Japanese Patent Application Laid-Open No. 62-122918 and Japanese Patent Publication No. 44 -18473, both covering apparatuses developed by the present applicant prior to this application.
- These prior art apparatuses are of such arrangement that, as FIG. 7 shows, two horizontally opposed
suction belts flat tube 5 is progressively spread and opened as it is transported by thebelts belts carrier device 30 for effecting ascent and descent and horizontal movement of anobject 8 such as a container. - According to such arrangement, an
object 8 supplied to position below the openedtube 5 is elevated and inserted into thetube 5, which is then transported forward until thetube 5 is separated from thebelts tube 5 is fitted over theobject 8. - Such arrangement permits easy spreading and opening of flat tubes in the course of transport thereof and, as compared with other known arrangement such that a flat tube is spread and opened by means of a mandrel to a configuration conforming to the shape of the object to be wrapped, the arrangement is advantageous in that the apparatus is relatively simple in construction.
- With the aforementioned prior art arrangement, however, one drawback is that since the insertion of each
object 8 into an openedtube 5 is carried out through ascent and descent, as well as horizontal movement, of theobject 8 by means of the holder-carrier device 30, a very complicated mechanism is required for drive control of the holder-carrier device 30 for such ascent and descent and horizontal movement, which leaves much yet to be improved with respect to the holder-carrier device 30 from the standpoints of ease of manufacture and manufacturing cost economy. - Another drawback is that the track of movement of the
object 8 such that theobject 8 is moved vertically upward and then moved horizontally does not permit smooth movement and is therefore unsuitable for use where high speed operation is required. - A further drawback is that the arrangement in which the
object 8 is moved upward from a location immediately below the openedtube 5 for insertion thereof into thetube 5 does not permit accurate insertion, unless thetube 5 is held open substantially wider relative to the external size of theobject 8. Moreover, as a matter of reality, thetube 5 as spread and opened by and between thebelts tube 5 is not so much different from the outer diameter of theobject 8, therefore, thetube 5 and theobject 8 may interfere with each other at the moment of theobject 8 being inserted into thetube 5, which poses a problem in terms of insertion accuracy. - It is a primary object of the invention to eliminate the necessity of moving an object to be wrapped through a complicated process of movement including vertical and horizontal movement and to enable accurate fitting of an opened tube over the object by a simplified apparatus and process of operation.
- The invention is directed to solving the aforementioned problems with the prior art by fitting the tube and the object into engagement with each other by moving one of them gradually toward the other while the tube and the object are transported in same direction.
- According to a first aspect of the invention there is provided an apparatus for opening a flat tube and fitting same on a container or the like, comprising a pair of cyclically moving
members flat tubes 5 successively while transporting thetubes 5 by holding them at opposite side portions thereof, and atransport device 7 disposed below said pair of cyclically movingmembers objects 8 to be wrapped in same direction as that in which theflat tubes 5 are transported by said cyclically movingmembers tubes 5 to be moved successively towardindividual objects 8 for being fitted thereon from above as theobjects 8 are transported by thetransport device 7. - According to a second aspect of the invention there is provided an apparatus for opening a flat tube and fitting same on a container or the like, comprising a pair of cyclically moving
members flat tubes 5 successively while transporting thetubes 5 by holding them at opposite side portions thereof, and atransport device 7a disposed above said pair of cyclically movingmembers objects 8 to be wrapped while supporting them at top side in same direction as that in which theflat tubes 5 are transported by said cyclically movingmembers transport device 7a having a transport path comprising a forwardly down-sloped portion C for enablingindividual objects 8 to be moved successively towardindividual tubes 5 for being inserted thereinto from above as thetubes 5 are opened while being transported by the cyclically movingmembers - According to a third aspect of the invention, in the apparatus of the second aspect, instead of the provision of said forwardly down-sloped portion C in the transport path, said cyclically moving
members 2, 2b being forwardly up-sloped to enable individual openedtubes 5 to be moved successively towardindividual objects 8 for being fitted thereon from below as theobjects 8 are transported by thetransport device 7a. - In the foregoing arrangement of the first aspect,
individual tubes 5, transported and opened by the cyclically movingmembers transport device 7 in forwardly down-sloped fashion, are moved successively towardindividual objects 8 as they are transported forward, so that thetubes 5 are individually fitted over theobjects 8 from above. Thus, operation of such fitting can be performed without requiring such complicated process for transport ofindividual objects 8 as that employed in the prior art which involves ascent and descent, as well as horizontal movement, of theobjects 8. - The respective paths of movement of the
tubes 5 and of theobjects 8 are codirectional, and eachtube 5 while being spread and opened is gradually moved downward for being fitted on eachcorresponding object 8. This permits accurate partial fitting of thetube 5 on a top portion of theobject 8 at an intial fitting stage, even when thetube 5 is not wide open. Thetube 5 continues to move downward further after the initial fitting thereof on the top of theobject 8 and accordingly thetube 5 is fitted on theobject 8 as it is opened wider while being guided along the outer periphery of theobject 8. Therefore, fitting operation can be accurately performed without possible hang-up or the like trouble with thetube 5 relative to theobject 8. - According to the arrangement of the second aspect,
individual objects 8, as they are transported along the forwardly down-sloped portion C of thetransport device 7a disposed above the cyclically movingmembers individual tubes 5 being opened in their travel below the path of theobjects 8 and are thus individually fitted into thetubes 5 from above. - According to the arrangement of the third aspect,
individual tubes 5 opened as they are transported by the forwardly up-sloped cyclically movingmembers transport device 7a are moved successively towardindividual objects 8 being transported by thetransport device 7a and are fitted on theobjects 8 from below. - Therefore, the arrangement according to either the second aspect or the third aspect enables successful insertion or fitting without requiring each
object 8 to be passed through such a complicated process of movement as required in the prior art, including ascent and descent and horizontal movement. Theobject 8, with its bottom positioned opposite to the mouth of atube 5 being spread and opened, is partially inserted downward into thetube 5 and is then lowered relative to thetube 5 as thetube 5 is further spread and opened along the outer periphery of theobject 8. This insures accurate insertion of theobject 8 into thetube 5. - As described above, the apparatus of the invention comprises a pair of cyclically moving members operative to spread and open flat tubes while advancing the tubes, and a transport device provided below or above the cyclically moving members for transporting objects to be wrapped in same direction as the direction in which the flat tubes are transported, the track of movement of the transport device or that of the cyclically moving members being inclined in such fashion that the one gradually approaches the other, so that individual objects can be inserted successively into individual tubes from above as the latter is spread and opened while being advanced. Therefore, fitting operation with respect to the tubes relative to the objects can be performed without requiring such complicated process of movement of the objects as involved in the prior art, including ascent and descent and horizontal movement. Such arrangement means simplified construction of the transport device, which insures considerable reduction in the manufacturing cost of the apparatus. The arrangement permits smoother transport of the objects and, additionally, it facilitates synchronous operation of the transport device and cyclically moving members, which means that the apparatus can suitably be employed for high speed operation.
- Moreover, according to the invention, in which each tube and each object to be wrapped, in corresponding relation, are transported in same direction and, in the course of such transport, one of the two is gradually fitted on or inserted into the other from above, even if the tube is not wide open at an initial stage of tube fitting relative to the object, operation for inserting the object into the tube involves no such difficulty as has been encountered with the prior art arrangement in which the object is inserted into the tube from a direction perpendicular to the direction of transport of the tube, it being possible to effect accurate partial fitting of the tube relative to a portion of the object. The tube allows the object to be further inserted thereinto as it is further spread and opened while being guided along the outer periphery of the object. This insures accurate tube fitting. Thus, the invention provides considerable improvement in tube fitting accuracy over the prior art arrangement and has an additional advantage that the tube can be properly fitted on the object even if it is a small-diameter tube having no much difference in size from the object.
- The apparatus of invention is also advantageous in that it is well adaptable for any change in the size of the object to be wrapped or the position for tube fitting, by suitably changing the distance between the leading ends of the cyclically moving members and/or the level of the track of transport of the cyclically moving members or of the transport device for transport of objects, or otherwise, which fact adds to the practical applicability of the invention.

- Preferred embodiments of the invention will now be described.
- In FIG. 1,
numeral 7 designates a transport device for transporting containers 8 (objects to be wrapped) on and along ahorizontal path 11. Thetransport device 7 comprises a pair ofside belts pulleys side belts transport path 11. Theside belts attachments side belts individual containers 8 supplied onto thetransport path 11 to successively push thecontainers 8 forward. Therefore, thetransport path 11 need not necessarily have a function to positively transport the containers, but it may be comprised of a drive belt of a belt conveyor or the like. - Above the
transport device 7 there is provided adevice 1 for transporting and openingflat tubes 5, whichdevice 1 will be described below. - In FIG. 1 (c), 2, 2a designate a pair of cyclically movable suction belts (which correspond to cyclically moving members) with air permeability which are arranged in opposed relation and guided by a plurality of pulleys, the
belts belts container transport path 11 of thetransport device 7 in straddling fashion. - Inside the
suction belts vacuum suction chambers 4, 4a operative to apply vacuum force of suction through the airpermeable belts feeder unit 6 for supply offlat tubes 5 is disposed beside the onesuction belt 2a, thefeeder unit 6 being such that after a continuous tube is cut by a cutter into pieces of desired size, the cut tubes are supplied onto thebelt 2a for being sucked onto the outer surface of the latter. - The arrangement of the embodiment having now been described, the manner of operation will be explained by way of example.
- Desired
flat tubes 5 having prints or the like suitably applied thereto are first supplied successively by thefeeder unit 6 onto the outer surface of the onesuction belt 2a of the tube opening andtransport device 1 at predetermined intervals for being held in suction thereagainst so that thetubes 5 are delivered into the space between the pair ofbelts flat tubes 5 are then held in suction at opposite sides by and between the twobelts suction belts individual tubes 5 are gradually moved downward towardindividual containers 8 transported on thetransport device 7 at the predetermined pitch so that thetubes 5 are individually fitted on thecontainers 8. - At an initial stage of the process of each
tube 5 being fitted on acontainer 8, thetube 5 partially fits on a top portion of thecontainer 8 as may be seen at M in FIG. 1 (a), and therefore accurate fitting can be achieved even if thetube 5 is not wide open. Subsequently, as thetube 5 is opened wide while being transported forward, thetubes 5 is further fitted on thecontainer 8 toward a larger diameter portion thereof while being guided along the outer periphery of thecontainer 8. This insures more accurate tube fitting. - Both each
tube 5 and eachcontainer 8 are transported in same direction, and thetube 5 is gradually moved downward toward thecontainer 8 for being fitted on the latter from above. Therefore, the movement of thetube 5 can easily be synchronized with that of thecontainer 8 and, even during high speed operation, thetube 5 can be accurately fitted on thecontainer 8. - After each
tube 5 is satisfactorily fitted on acontainer 8, thetube 5 as is fitted on thecontainer 8 is transported forward by thetransport device 7 for transfer to a next following stage. At the next stage, the process of, for example, heat shrinking thetube 5 for bringing it into bond with the side of thecontainer 8 is carried out. - It can be arranged that holding in suction of each
tube 5 by thebelts tube 5 on thecorresponding container 8 ends. Through such arrangement it is possible to smoohly effect shifting of thetube 5 toward thecontainer 8. Such arrangement can readily be adjusted by suitably setting the position of thechambers 4, 4a operative to apply vacuum force through thebelts tube 5 is still held in suction against thebelts tube 5 can readily be separated from thebelts container 8, with no inconvenience being caused to the process offitting tubes 5. - In the above described embodiment, each
tube 5 is fitted on eachcorresponding container 8 to the bottom thereof. Where thetube 5 is used as a shrink label or the like, however, there may be cases where it is desired that thetube 5 should be partially fitted on thecontainer 8, for example, only on an upper portion thereof. The present embodiment is suitably applicable in such case. - The apparatus shown in FIG. 2 is identical in fundamental features with the apparatus of Embodiment 1 ( therefore, devices and parts similar to those of
Embodiment 1 are designated by like reference characters, which applies to other embodiments as well). -
Attachments 14b, 14c projecting fromside belts transport device 7 for transport of containers are adapted toabut containers 8 at a predetermined level to enable thecontainers 8 to be transported forward.Heating units suction belts - According to the arrangement of the present embodiment, when each
tube 5 spread and opened between thesuction belts corresponding container 8, thetube 5 is stopped byattachments 14b, 14c so that it is not allowed to descent to the level of the bottom of thecontainer 8. When, after fitting of thetube 5 has ended, thetube 5 is heat-shrunk through heating by theheating units container 8. Thus, thetube 5 is no longer liable to drop toward the bottom of the container upon subsequent movement of theattachments 14b, 14c away from sides of thecontainer 8. Accordingly, thecontainer 8 with thetube 5 as fitted in position on the upper portion of thecontainer 8 can be supplied to a next following operating stage. - In the first and second embodiments described above, the transport device for container transport is constructed as a conveyor provided with attachments for pushing containers forward. However, the construction of the
transport device 7 in the invention is not limited to that shown in the embodiments. For example, thetransport device 7 may be in the form of a general-purpose conveyor having no side belt or the like, such thatcontainers 8 are loaded and carried forward on the conveyor. However, for the purpose of transporting light-weight containers, it is desirable from the standpoint of practical applicability to employ a transport device having a positioning function forcontainers 8 so as to prevent possible deviation incontainer 8 positioning. For such transport device, one as shown by way of example in FIG. 3 may be employed such thatcontainers 8 are transported while being held in suction on abelt 16 provided with venting holes or the like for application of vacuum suction force. - Where a
tube 5 is partially fitted on an upper portion of acontainer 8,attachements 14b, 14c for stoppingtubes 5 as in the above mentioned embodiment can be employed which concurrently serve for the transport of containers. This arrangement is desirable from the standpoints of apparatus streamlining and simplification, but it is understood that the invention is not limited by such arrangement. For example, theattachments 14b, 14c may be separate from thecontainer transport device 7 and, without their being used for clamping containers, they are transported synchronously withcontainers 8 so that theattachments 14b, 14c are used only for the purpose of stoppingtubes 5. It is noted that for the purpose of stoppingtubes 5, the attachments may be arranged at spaced locations corresponding to front and rear sides ofindividual containers 8, irrespective of whether or not they are abuttable in relation to thecontainers 8. The configuration of such attachments is not limited in any way. There is no particular limitation with respect to drive means for the attachments. Such attachments may be provided at locations corresponding to any one of the following positions: front, rear, or side of eachcontainer 8. Depending upon the shape of eachcontainer 8 and the tube fitting position with respect to thecontainer 8, such attachment need not necessarily be provided. Where no such attachment is provided, theside belts tube 5 fitted on acontainer 8 is placed on edge portions of theside belts - Nextly, a third embodiment of the invention will be explained with reference to FIG. 4.
- In FIG. 4, 1a designates a device for opening and transporting flat tubes, which is identical with the like device of
Embodiment 1 except that thebelts - Shown by 7a is a container transport device provided above the
belts Numeral 17 designates a drive chain which is cyclically driven while being guided by a plurality ofpulleys 18 ... of thetransports device 7a. The underside track of thedrive chain 17 has an up-sloped portion A, a horizontal portion B, and a forwardly down-sloped portion C. Thedrive chain 17 has on its outer surface side a plurality of outwardly projectingpush pieces 19 arranged at a predetermined pitch. Container support guides 20 are provided in parallel relation to the underside track of movement of thedrive chain 17. As FIG. 4(c) shows, each of the support guides 20 serves to lock and support acollar portion 22 formed on the top of eachcontainer 8. - According to the arrangement of this embodiment,
containers 8 supplied onto afeed conveyor 21 can be transported along the support guides 20 by being pushed by means of thepush pieces 19 of thetransport device 7a. In that case, the bottom side of eachcontainer 8 is in non-supported condition. - After each
container 8 has reached the forwardly down-sloped portion C, thecontainer 8 is lowered as it is advanced, so that thecontainer 8 is gradually inserted into atube 5 therebelow which is being opened and transported between thesuction belts - In this tube fitting operation, as in the foregoing
Embodiment 1, eachtube 5 and eachcontainer 8 are transported in same direction . Further, thecontainer 8 is gradually inserted into thetube 5 from above. Therefore, the movement of thetube 5 and that of thecontainer 8 can easily be synchronized. Although thetube 5 is not wide open at an initial stage of the process of thecontainer 8 being inserted into thetube 5, accurate insertion can be effected, because thecontainer 8 is only partially inserted at its bottom side into thetube 5. Subsequently, as thetube 5 is transported forward and opened wide, a larger-diameter portion of thecontainer 8 is properly inserted downward into thetube 5. In this case, thetube 5 can be fitted in position as it is opened by being guided along the outer periphery of thecontainer 8, which insures accurate completion of fitting operation. - Upon completion of the insertion of the
container 8 into thetube 5, the tube-fittedcontainer 8 is pushed forward bypush pieces 19 on thetransport device 7a, being thereby loaded onto a separately provideddischarge conveyor 23, which in turn delivers the tube-fittedcontainer 8 to a next following stage of operation. - In the above described embodiment, the
transport device 7a has an up-sloped portion A. This enables receiving supply ofcontainers 8 from thefeed conveyor 21 installed at a substantially same level as thesuction belts conveyors - The construction of the
transport device 7a is in no way limited to the above described one. Where thecontainer 8 has nocollar portion 22, for example, a conveyor for transportingsuch container 8 while holding a top portion thereof under vacuum suction may be employed. Any such change in design may be made as desired. There is no limitation as to the slope, size, and other details of the forwardly down-sloped portion C. The entire track range for transport ofcontainers 8 on thetransport device 7a may be inclined so that it consists entirely of a sloped portion C. - This embodiment is a modified form of the above described Embodiment 3 and will be explained with reference to FIG. 5.
- A
transport device 7a is designed to transportcontainers 8 while holding them at the top thereon. The transport track of thedevice 7a has no sloped portion and accordinglycontainers 8 are horizontally transported. Cyclically movingmembers transport device 7a are forwardly up-sloped. - In this embodiment,
tubes 5 as opened while being transported by the cyclically movingmembers containers 8 for being fitted on thecontainers 8 from the bottom side thereof. Therefore, just as seen in the above described Embodiment 3, the present embodiment permits accurate fitting without requiring any complicated process of transport fortubes 5 andcontainers 8. - In the foregoing embodiments,
suction belts opening tubes 5. However, it is understood that the invention is not limited by such belts. A device in which a holder having a vacuum suction function as disclosed in Japanese Patent Publication No. 44 - 18473 shown as an example of the prior art is cyclically movable may be employed, for example. Of course, other suitable means may be used. It is only necessary that the device comprises a pair of opposed cyclically movingmembers flat tubes 5 while transporting thetubes 5 by holding them at opposite side portions thereof. - In the foregoing embodiments, the object for tube fitting is exemplified by a container. However, the scope of application of the invention is not limited to such kind of object, and the invention may be applicable to various other kinds of objects. Likewise, various kinds of
flat tubes 5 may be used, and they are not limited to shrink labels or cap seals of the heat shrink type. - According to the invention, where the cyclically moving
members flat tubes 5 are forwardly down-sloped, not entire track range of tube transport of the cyclically movingmembers transport device 7a for transport ofobject 8 has a forwardly down-sloped portion C. For example, even where the cyclically movingmembers members - Further, it is possible to provide a forcing
unit 40, as shown in FIG. 6, for forcing atube 5 fitted on eachobject 8 into position relative to the object at a downstream location in thedevice 1 for transporting and opening flat tubes. The forcingunit 40 has an up and downmovable arm 41 positioned above the object, thearm 41 being provided at its lower end with apad 42 adapted to abut the top of thetube 5 fitted on theobject 8 for forcing the tube down. Through the provision of such forcing means it is possible to achieve more accurate fitting of thetube 5 in position relative to the object, even if thetube 5 is not properly positioned when it is fitted on theobject 8. - Various changes in design may be made as desired with respect to the details of the arrangement of parts, within the spirit and scope of the invention. There is no limitation whatever as to means for feeding
tubes 5 to the cyclically movingmembers heating units 15 for heat-shrinkingtubes 5 passed through the process of tube fitting relative toobjects 8 is, needless to say, applicable to only such partial tube fitting operation as exemplified in the foregoingEmbodiment 2.
